According to the newspaper, Trump Jr. arranged a meeting with Russian lawyer Natalia Veselnitskaya several weeks after his father secured the Republican presidential nomination.

While the reports in the Times described Veselnitskaya as having ties with the Kremlin, a spokesperson for Russian President Vladimir Putin on Monday said the Kremlin does not know the lawyer.

Trump Jr. said in a statement to the Times on Sunday that he had met with Veselnitskaya, who has reported ties with the Kremlin, at the request of an acquaintance, but denied that he received any information on Clinton.

Trump Jr. said Monday that he would be “happy” to speak to the Senate Intelligence Committee about the meeting.

“Happy to work with the committee to pass on what I know,” Trump Jr. tweeted Monday.
